Starting May 2, AT&T will start putting caps on people who surf the internet just a tad bit too much, according to DSLReports.

AT&T DSL users will be capped at 150GB, while AT&T U-verse users will get a slightly higher allowance at 250GB.

Users will probably want to be pretty careful about going over as there are penalties. Customers get to exceed the data cap three times across the life of the account, before they are asked to pay $10 for every 50GB.

AT&T will begin sending out notices later this month, starting March 18. Luckily, customers will be alerted about how much more data they have left as they slowly creep up to the limit.
